Invoicing

THL accepts only electronic invoices compliant with the European standard. If you do not have a system capable of producing e-invoices, you can use the government’s Handi service to create and send them. Instructions and additional information about the Handi service are available on the State Treasury website:
Invoicing the state (State Treasury)
